Surgetus neeg raug ntesyog ib qho khoom siv insulating siv los tiv thaiv qhov system ntawm overvoltage.Zinc oxide surge arrester yog ib hom kev tiv thaiv overvoltage uas tau siv dav hauv lub zog hluav taws xob.Zinc oxide ntes los ntawm porcelain los yog iav insulator, valve, tsau bolts thiab lwm yam khoom.Nyob rau hauv xyoo tas los no, ZnO tus neeg ntes feem ntau yog siv hauv lub zog hluav taws xob, uas tuaj yeem tiv thaiv qhov system ntawm overvoltage.
Qauv
Zinc oxide ntes los ntawm lub tes tsho plooj (porcelain), valve, tsau bolts thiab lwm yam khoom.Main qauv:
1. Cov ntaub ntawv ceramic insulator yog iav, alumina thiab zinc oxide, thiab zinc oxide xob laim ntes ua los ntawm cov ceramic insulator muaj kev ua haujlwm zoo rwb thaiv tsev, ntim me me thiab lub teeb yuag, thiab yog cov khoom siv dav siv hauv kev tiv thaiv hluav taws xob.
2. Valve disc: muaj ib los yog ntau tshaj li niaj zaus zoo li tus hlau films, xws li zinc oxide, hlau ntawv los yog iav ntawv ci.Lub teeb ntes hluav taws xob tuaj yeem siv los tiv thaiv cov khoom siv hluav taws xob los ntawm overvoltage hauv lub zog hluav taws xob.
3. Kev kho bolts yog siv los txuas thiab txhawb nqa ntawm qhov kho lub valve thiab lub rooj zaum valve.
Txoj cai ntawm kev ua haujlwm
Zinc oxide xob laim ntes yog tsim los ntawm valve piece, porcelain insulator (los yog iav insulator), kho ntsia liaj qhov rooj thiab lub tes tsho porcelain.Lub xob laim impulse tam sim no raug txwv los ntawm qhov dhau-voltage absorbing keeb ntawm lub valve.Cov txheej txheem cov nyhuv yog raws li nram no: thaum xob laim yoj invades, lub xob laim ntes tam sim ntawd absorbs zog thiab tsim ib tug loj zog zaus tam sim no los ntawm lub valve daim;Yog hais tias xob laim yoj txuas ntxiv mus thiab lub valve daim tseem tuaj yeem ua kom zoo rwb thaiv tsev lub xeev, cov seem seem nyob rau hauv cov hluav taws xob ntes tau tawm vim qhov seem ntawm qhov seem ntawm lub valve poob qis dua tus nqi ntsuas hluav taws xob.
Txoj Cai Ua Haujlwm ntawm Surge Arrester: Thaum Surge Arrester tsim lub zog zaus tam sim no, nws lub peev xwm tso tawm muaj feem cuam tshuam rau qhov poob siab absorbing peev xwm ntawm Surge Arrester thiab qhov seem seem ntawm lub valve;Thaum lub overvoltage yog ib qho nqi ntsuas, Surge Arrester yuav tso tawm ntau tus nqi los ntawm varistor ntawm lub valve hlais yam tsis muaj kev puas tsuaj.
Yam ntxwv
(1) Me me, lub teeb yuag thiab tsis muaj suab nrov.
(2) Muaj peev xwm tiv taus dhau-voltage, thiab muaj peev xwm tiv taus hluav taws xob zaus voltage thiab impulse tam sim no.
(3) Nws yuav tsum muaj hluav taws xob zoo thiab thermal kev ua tau zoo thiab me me thiab ruaj khov kub coefficient.
(4) tsis muaj qhov seem seem, lub neej ua haujlwm ntev thiab siv tau zoo.
(5) Kev ua haujlwm siab thiab kev tsim khoom yooj yim.
Raws li cov cuab yeej tiv thaiv dhau-voltage hauv lub zog hluav taws xob, ZnO tus neeg ntes tau ua lub luag haujlwm tseem ceeb hauv kev nyab xeeb ntawm cov khoom siv hluav taws xob thiab hluav taws xob.Nrog rau kev tsim hluav taws xob hauv peb lub teb chaws, daim ntawv thov ntawm MOA yuav ntau thiab ntau dua.Nyob rau hauv cov txheej txheem ntawm daim ntawv thov, peb yuav tsum ntxiv dag zog rau kev soj ntsuam ntawm kev ua tau zoo ntawm tus ntes, txhim kho lub installation technology thiab txij nkawm zoo, zam cov khoom puas tsuaj vim yog vim li cas, thiab xyuas kom meej kev ruaj ntseg thiab txhim khu kev qha kev khiav hauj lwm ntawm cov khoom siv hluav taws xob thiab daim phiaj hluav taws xob.
